Abstract
Official abstract text for this publication.
A seat frame manufacturing method including: performing extrusion molding of a metal material to form a workpiece material, which has a closed section shape or a solid section shape in which a plate piece continuous in an extrusion direction protrudes in a protruding direction from a portion thereof; and performing press working, the press working including bending a part of the plate piece of the workpiece material in an out-of-plane direction of the plate piece, which is different from the protruding direction of the plate piece, to obtain a finished product.
First claim
Opening claim text (preview).
What is claimed is: 1 . A seat frame manufacturing method comprising: performing extrusion molding of a metal material to form a workpiece material, which has a closed section shape or a solid section shape in which a plate piece continuous in an extrusion direction protrudes in a protruding direction from a portion thereof; and performing press working, the press working including bending a part of the plate piece of the workpiece material in an out-of-plane direction of the plate piece, which is different from the protruding direction of the plate piece, to obtain a finished product. 2 . The seat frame manufacturing method according to claim 1 , wherein the out-of-plane direction of the plate piece is a direction substantially perpendicular to the protruding direction of the plate piece. 3 . The seat frame manufacturing method according to claim 1 , wherein the extrusion molding is performed so as to form the workpiece material having the closed section shape in which the plate piece continuous in the extrusion direction protrudes in the protruding direction from the portion thereof. 4 . The seat frame manufacturing method according claim 1 , further comprising: cutting the plate piece so as to change a protruding length of the plate piece depending on portions, the cutting being performed between the extrusion molding and the bending. 5 . The seat frame manufacturing method according to claim 1 , wherein the extrusion molding is performed such that a thickness of the workpiece material is partially changed. 6 . The seat frame manufacturing method according to claim 1 , wherein the press working includes forming a groove portion to the plate piece, the groove portion extending in a direction in which bending rigidity of the plate piece can be enhanced. 7 . The seat frame manufacturing method according to claim 1 , wherein the finished product is used as a framework of a seat back of a vehicle seat.
